Patent ES-418906-A1 (ES)
Title: Stabilized side plate construction for grate conveyor
IPC: F27B21/08
Filed: 1973-09-19
Abstract: A stabilized side plate construction for a grate conveyor or the like in which one side plate of each pair of pivotally connected side plates has loosely keyed thereto a flanged spool which is journalled for pivotal movement on the reduced diameter extension of a chain pin or, alternatively, on the reduced diameter extension of the thru rod of the conveyor, with the flange of the spool abutting a radial shoulder of the larger diameter portion of the chain pin or of the thru rod, as the case may be, for proper orientation of the spool at a fixed reference location on the chain pin or on the thru rod. The other side plate of the pair of pivotally connected side plates is pivotally movable relative to the spool shoulder although the spool shoulder does not necessarily serve as a bearing for the other side plate. A washer which, in effect, is the opposite flange of the spool, is retained on the chain pin reduced diameter extension, or alternatively, on the reduced diameter extension of the thru rod, at a fixed lateral spacing from the spool flange, whereby to restrict the two pivotally connected side plates to a dimensionally predetermined limited relative lateral movement therebetween, thus minimizing the "wobble" between pivotally connected side plates.

Patent ES-428612-A1 (ES)
Title: Variable pressure hydraulic system
IPC: F15B11/05
Filed: 1974-07-24
Abstract: A variable pressure hydraulic system in which a motor is operated by a variable displacement pump whose displacement is regulated by a control valve which is sensitive to the pressure at the hydraulic motor to maintain the pump outlet pressure higher than the motor pressure. A normally open solenoid-controlled valve is movable upon actuation of the solenoid to a closed position in which it blocks communication between the control valve and the hydraulic motor. The electrical circuit for the solenoid valve includes a pressure sensitive switch responsive to the fluid pressure at the hydraulic motor so that when the fluid pressure at the hydraulic motor reaches a predetermined value, the solenoid is activated to close the solenoid-controlled valve and block communication between the control valve and the hydraulic motor. In this manner, the maximum pressure of the system is limited.

Patent ES-443102-A1 (ES)
Title: Seals
IPC: B65D85/18
Filed: 1975-11-29
Abstract: Polythene bags are used to group together articles of clothing for transit. The invention relates to a security seal for use with such bags to prevent undetected transit theft. The seal according to the invention has two strip-like portions, which are formed with latching portions at points along the lengths of the strip-like portions.

Patent ES-462338-A1 (ES)
Title: Method of regenerating asynchronous data signals and apparatus for performing the method
IPC: H04L25/38
Filed: 1977-09-14
Abstract: A method and a device is described for the regeneration of asynchronous data signals of a given character structure which arrive on a transmission line time distorted and at a signalling rate which deviates from the nominal signalling rate and after detection are fed to a regeneration device at a character rate determined by the arriving data signals, the data signals then being retransmitted at a signalling rate determined by a timing generator included in the regeneration device. In order to reduce variations in character length of the retransmitted data signals, at least part of the characters fed to the regeneration device are stored temporarily while a preceding character is being retransmitted, and the length of a retransmitted character is shortened in dependence upon the separation in time between the beginning of a character fed to the regeneration device and the expected ending of a character in progress of retransmission, the degree of the shortening being determined by the relation of the time separation to a definite time limit.

Patent ES-467909-A1 (ES)
Title: Method and apparatus for centrifugal casting
IPC: B22D13/10
Filed: 1978-03-16
Abstract: Tubular metal articles are produced by centrifugal casting in a rotary metal mold lined by centrifugally distributing a quantity of a dry finely particulate free flowing refractory material on the active mold surface with the quantity being in excess of that required for the lining, densifying the layer by rotating the mold at a rate such that the refractory layer is subjected to centrifugal force adequate to establish an equivalent specific gravity of at least 7.5, determined by multiplying the actual specific gravity of the refractory material by the number of gravities of centrifugal force, contouring the densified layer and removing the excess refractory material, rotating the mold at the casting rate and then introducing the molten metal for casting while continuing to rotate the mold at least that rate. Articles so cast have relatively smooth outer surfaces which require only finish machining. The invention employs no additives and thus eliminates the need for venting the metal mold, provides a relatively thick lining of predetermined insulating capability so as to control the grain structure of the cast metal, eliminates the usual end cores, and allows the refractory material to be recycled. The invention is particularly useful for casting articles, such as cylinder liner blanks, from grey iron, such articles having an outer enlargement, typically a transverse outer end flange. Cast according to the invention, such articles have Type A graphite throughout the entire inner surface and for at least a substantial portion of the thickness of the flange or other outer enlargement.
